The proposed new method partially solves the problem of low signal-to-noise-ratio (SNR) when modulation frequency increases. In this paper, we suggest to keep constant the amplitude of the detected photoacoustic (PA) signal by linearly increasing the modulation voltage versus frequency. The PA signal of the sample can be easily estimated by fast Fourier-transform. It is also demonstrated that the presented method is able to detect a subsurface flaw in a graphite in the 10-100 Hz frequency range.
